METHOD OF FORMING SOCKETS OF SEPARABLE FASTENERS FOR GLOVES, &c.

SPECIFICATION forming part of Letters Patent No. 664,243, dated December 18, 1900.

Application filed J une 4., 1900. Serial No. 18,943. (No model.)

T0 all whom it may oon/cern:

Beit known that LWILLIAM B. H. Dowsn, of

Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Methods of Forming the Sockets or Female Members of Separable Fasteners Design ed Especially for Gloves and other Articles of Wearing-Apparel, of which the following, taken in connection with the accompanying` drawings, is a specification.

My invention relates to a method of forming the socket or female member of a separable fastener designed especially for gloves and other articles of wearing-apparel.

The object of the invention is to provide a method of assembling and securing the parts of the female member of 'a fastener whereby the material to which the fastener is applied will form the cap or cover of the female member, thereby insuringa correspondence in nish, shade, and appearance between the cap or cover of the fastener and thematerial to which it is attached.

The steps constituting theimproved method will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and pointed out in the appended claims.

In the drawings, Figure 1 is an elevation of the elements or parts from which the female member of the fastener is formed, said parts being separated, but arranged in proper relative positions ready for assemblage by my improved method. Fig. 2 is a sectional View of the parts when brought together preparatory to being united permanently, and Fig. 3 is a sectional view of the female fastener member complete applied to the material.

The reference-letter B designates the material to which the fastener member is secured, A a plain metallic ring, and C the socket-case of concavo-convex form and provided with an annular flange D. Between the case C and its flange D a contracted neck E is formed.

In carrying out my method the case C is placed on the under side of the material B and the ring A on the upper side thereof, passing over the case and the portion f of the material which rests thereon. This brings the ring to a position above and parallel to the flange D of the case and rmly binds the material between the case and ring.

The final step in the method is to flatten the case by pressure, causing it to expand circumferentially slightly beyond the inner diameter of the ring A, thus securing the cap within the ring and at the same time smoothly spreading the material B over the case to form the cap or cover of the fastener.

Y The crushing pressure applied to the top of the case through the material is diverted in its effect by providing a yielding counter pressure on the under side of the case C, in the central part thereof,`which pressure being exerted in opposition to the crushing pressure supports the central part of the case C and confines the crushing or flow of metal tothe edges thereof. Thus the pressure is so applied as to preserve the convexity of the crown of the case, the iiow of the metal under pressure beingconfined to the rim or sides of the case.

It will be obvious that the method above described may be carried out by any suitable dies or implements for eecting the required pressure on the case, the invention residing in the method and being independent of any particular mechanism.

I claiml. The method of coveriugand setting a socket-caseof a fastener, which consists in placing said socket-case on the under side of the material, then fitting a retaining element over the material and socket-case, and then Vsubjecting the socket-case to such a crushing pressure as to cause the flow of the metal in the crown of the socket-case to be restrained and directed to the sides thereof and the conveXity of the metal from side to crown preserved.

2. The method of setting and covering a cup-shaped fastener-case, which consists in placing the fastener-case on the under side of the material to which it is to be set, then placing a ring over the material and fastenercase, and then subjecting the fastener-case to positive crushing pressure at the rim thereof and yielding confining pressure at the crown thereof, whereby the flow of metal is prevented at the crown of the case and diverted to the sides thereof.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 28th day of May, A. D. 1900.

WM. B. II. DOWSE.
